Possible signals from lost jet's black boxes heard

PERTH, Australia (AP) — U.S. Navy equipment has picked up signals consistent with the pings from aircraft black boxes, an Australian search official said Monday, describing the discovery as "a most promising lead" in the nearly month-long hunt for the missing Malaysia Airlines plane.

Angus Houston, the head of a joint agency coordinating the search in the southern Indian Ocean, called it "very encouraging" but said it may take days to confirm whether signals picked up by the ship Ocean Shield are indeed from the flight recorders on Flight 370.


The Australian navy ship Ocean Shield, using a U.S. Navy towed pinger locator, detected the sounds on two occasions over a period totaling more than two and a half hours.
"Clearly this is a most promising lead, and probably in the search so far, it's probably the best information that we have had," Houston said at a news conference.
"This would be consistent with transmissions from both the flight data recorder and the cockpit voice recorder," he said.
He said the position of the noise needs to be further refined, and then an underwater autonomous vehicle can be sent in to investigate.
"It could take some days before the information is available to establish whether these detections can be confirmed as being from MH370. In very deep oceanic water, nothing happens fast."
The plane vanished March 8 during a flight from Kuala Lumpur, Malaysia, to Beijing with 239 people on board, setting off an international search that started off Vietnam and then shifted to the southern Indian Ocean as information from radar and satellite data was refined.
The length of the search and lack of any information on the cause of the plane to go so far off course has transfixed the world, and made finding the black boxes important to finding a possible cause.
